lubricant for said gearing. With respect to said gearing, it 1s suiicient that the same be arranged, as shown, to rotate, the shafts 1 0 in pairs in opposite directions, the direction of rotation of the pulley 7 being in the direction of the arrow in Fig. 4, whereby the palls of spindles 10 will be rotated upwardly Mounted upon the bed plate 1, and substantially coeXtensive in length therewith, is a vertically movable table 11, the same being guided in said bed plate by rods 12 passing through apertures in the latter and having coiled therearound springs 13, tending normally to maintain said table 11 in its uppermost position. FiXedvto the ends of said table are guide plates 14, the width of the same corresponding with the thickness of the table, said plates projecting forwardly and widened at 14 and having their vertical ed es slightly beveled outwardly, as shown. he means for vibrating the table 11 vertically comprise a lever 15 fixed to a pivot rod 16 running transversely across the machine yand at its other end having fixed thereto a lever 17, said levers 15 and 17 being pivotally connected with the ends of the tabley 11 by suitable links 18, as shown. The free end of the lever 15 is guided by a strap 1,9'bolted to the side of the machine, said strap having an upper stop-screw 20 and a lower similar stopscrew 21 therein, whereby the vertical move.. ment of the free end of said lever 15 may be controlled as hereinafter described. Attached to said lever 15 intermediate its length is a rod 22, extending downwardly and connected to a suitable foot-lever (not shown.)

Mounted transversely of the table 11, and extending for some distance .forwardly thereof, are metal brackets 23, the same being disposed in mortises in the upper surface of said table and having mounted therein elongated anti-friction rollers 24 disposed to project but slightly above the top surface of the table 11, for a purpose hereinafter to be described. As an additional guide for the vertical movement of the table 11,1 provide suitable. slotted-'brackets 25 bolted thereto and projecting upwardly at the rearthereof, said brackets being engaged by pins 26 fixed to brackets 27 bolted. to the bed plate l, as shown in detail in Fig, 3. Also mounted on the. table 11 at the rear thereof are a plurality of angle irons 28 slotted to receive retaining screws 29, engaging the underside of the tablell, and' screws 30, in a manner readily understood.

The projecting spindles 10 are slotted at their outer'ends,'as best seen in Fig. 5, and have detachably mounted thereon coacting spindles 32, the same being provided with cross pins 33 to engage in'the slots in the ends of said spindles 10 to prevent inde- 1 pendent rotation'. Molded or` otherwise attached to said spindles '32 are elongated rolls 34 formed ofany suitable' soft material, preferably sponge rubber, said .rolls being tapered at their front ends topoints,-

as shown.

From the'v above description the operationd b of mv improved machine will be understood rari as follows: When it is desired to operate to action upon the lower edge of theJ rubberv l in Fig. 6 being that shown in Fig.' 3, while i Fig. 7 illustrates the relative position of the rolls. 34 and the forms when the'table 11 is depressed as described. The' operation of rolling the beads being completed by the depression of the foot treadle, the latter is rethe capacity of the machine, so far as its i' lengthisconcerned, all of the spindles l0 are provided with rollers 3.4, 'and the usualform-carrying board 35 having xed'there-Y to the forms 36, which previously have been dipped in the rubber solution to form thereon the articles, such as balloons, as shown,

is slid horizontally into position along the anti-friction rollers'24 from lthe front v'of the machine, the widened 'portions .14 of the guide plates 14 positioning the same with sufficientv accuracyduringthis operation until the rear edge of the board contacts with the stopplates2'8'. In this posil ment to the board 35 supported4 thereon.

tion -the width of the board 35 is such that it lhas passed completely beyond the widened portions 14 of the guide plates 14 and is free to move transversely of the machine. This action is highly desirable in order that thestems of the forms `36 passing between the pairs of bead-forming rolls 34 may come to position` -properly,1which is facilitated greatly by the action of the anti-friction rolls 24, which permit a free lateral Inove- Withthe board 35-E in position, which is stood that the rolls 34 are being rotated rapidly and in unison'from the pulley 7 the bead-forming operation may ybe effected' leased and the-table l1 resumes itsvnormal` uppermost position, its rise being limited definitely by the insertion of the successivei form-carrying boards: l *l d I have illustrated, in Fig. 2 a 'conventional dipping board 35,. which contains`two 'rows of forms 36, each row containing twelve forms. With amachine adapted to operate on such aboard, it ,will be seen that twenty? four articles are rolled at one operation of? said machine. It will be understood, however, that I do no t limit myself-to any par-h ticular'number'of forms, as it is evident that by elongating thev bead-,forming rollers 34 and similarly enlarging the table 11 later2 ally, two 'boards 35, or a board of double width .carrying forty-eightl'forms may be carried in thel machine andfoperated on simultaneously, In fact I do not wish to -limit myself in any respect as'to the num' ber of rows of forms 36 which may be operated on, as it is evident that they may be 4increased to` operate uponrsix or more rows results in bodily depressing the table 11, this movement beinglimited vby ,the position of the lower set-screw 21l in the strap 19,

through its contact with the free end of the lever 15. This movement of the table 11 causes the rollers 34 to 'exert their rolling of forms, though invthis case it may be nec-t essary to provide means for temporarily 'positioning and supporting the outer ends Iof the rollers 34 while in operation. Nor do` I wish toy limit 'myself to the lnumber `of forms 36 disposed longitudinally of fthe boards 35 as they ma, yvary in n'umber,as desired, the limit, of course, being that imposed by the number of rolls 34 on the may chine.

A VIt will be observed that the housing 5 A containing the gearing for carrying and operating the rollers 34 is removablefrom .the machine, and for the purpose of operating uponr different sized forms, I contem-l plate-the use of different 'sizedvhousingsv 5 shown in Figs. 3 and 4, and it-being underl carrying properly spaced spindles 10 to ac commodate forms of any character.- j In other words, .these dipped articlesare made various sizes, andthe stems-of the forms 36 vary more or less in size,.which renders K it desirable that a single machine may be capable of adaptation to these different sizes of spindles by thesubstitution of different housings 5 carrying suitable gearing and spindles'lO.v

As seen'in Fig. 1, the stop-screws 2O and l 21 may-be adjusted as desired to vary the.

' limit of movement in either direction of theh lever l5, which correspondingly will limit the movement of the table l1, whereby the latter may function properlywith forms of different lengths, and also may vary the length of the material rolled on the forms to suit different conditions, as may be desired. In a similar manner the angle irons 28 may be adjusted toward or from the rear edge of the table 11, to vary-the adjusted position thereon of the form carrying boards 35.,
